PostGIS Knows Where You Are

Should you be Worried?

Paul Ramsey has been working with geospatial software for more than 10
years, as programmer and consultant. He co-founded the PostGIS spatial
database project in 2001, and is currently an active developer and
member of the project steering committee. In 2008, Paul received the
Sol Katz Award for achievement in open source geospatial software.

Geolocation is a hot topic in technology right now,
so this topic will offer a tour of the terrain: what geolocation is
being used for, where PostGIS came from, how it uses PostgreSQL, who
is using it, and the technology challenges that PostGIS (and by
extension PostgreSQL) face in the future as use cases continue to push
more and more data through the system.
